Definitions

  • the present invention relates to packaged presliced ready-to-eat meat products, and methods of providing such products.
  • Sliced meat products such as ham, turkey and fully cooked beef have long been provided in prepackaged form for sale to consumers in grocery stores and the like. Such products often are sold in lidded tray packages that provide a rigid container for a robust packaging system.
  • Such packaging may optionally be hermetically sealed and may even include a modified atmosphere in order to extend shelf life.
  • the modified atmosphere most often includes a gas mixture of carbon dioxide, and nitrogen, or of carbon monoxide, carbon dioxide, and nitrogen. See, for example, Farber, “Microbiological Aspects of Modified-Atmosphere Packaging Technology—a Review,” Journal of Food Protection. Vol. 54. No. I. Pages 58-70 (January 1991).
  • the prepackaged meats as described above are generally not considered to be high quality, premium sliced meat products.
  • such meats typically are considered to be of ordinary quality.
  • such meats may contain preservatives that some customers would prefer to avoid, but which provide the conventional, pre-packaged sliced meats available from refrigerated display cases with an extended shelf life of up to 55 to 90 days.
  • prepackaged meats are advertised as premium sliced meat products, they are provided in robust packaging materials and hermetically sealed.
  • high quality sliced, ready-to-eat (i.e. already cooked, cooked and cured, or cured) meat products are conventionally provided in staffed meat outlets, such as butcher shops and deli counters, where the meat is provided to the outlet as sub-primal or large portion cuts that are further sliced by on-site human attendants according to the specific request of the customer.
  • staffed meat outlets such as butcher shops and deli counters
  • the meat is provided to the outlet as sub-primal or large portion cuts that are further sliced by on-site human attendants according to the specific request of the customer.
  • time has become a scarce commodity, and there is a great desire to obtain high quality, premium sliced meat products without waiting for extended periods of time at the deli counter.
  • the present invention makes it possible for the customer to obtain a shopping experience that is equivalent to the deli counter experience, while bypassing the inconvenience experienced by delay at the counter.
  • the shopper can quickly select high quality sliced, ready-to-eat meats having an acceptable shelf life from the display case.
  • a method for providing sliced ready-to-eat meat comprises slicing ready-to-eat meat in slices having a thickness of from about 0.5 to 10 mm to provide sliced ready-to-eat meat.
  • the sliced ready-to-eat meat is disposed into a flexible pouch component, which is flushed with a modified atmosphere comprising an inert gas and sealed to provide a sealed flexible pouch containing the sliced ready-to-eat meat and the inert gas.
  • the flexible pouch is formed from a material having:
  • a packaged sliced ready-to-eat meat product comprises ready-to-eat meat in slices having a thickness of from about 0.5 to 10 mm and a modified atmosphere comprising an inert gas disposed in a sealed flexible pouch.
  • the flexible pouch is formed from a film material having:
  • the present method and product may afford a number of benefits.
  • manufacturing efficiencies can be achieved through large scale production of sliced ready-to-eat meats at a centralized production facility.
  • High quality, premium sliced meats can be provided without the loss of productivity, product waste, and variation of sanitation standards that are inevitable from a decentralized and local slicing and packaging operations.
  • carrying out the slicing and packaging operations in a large scale production facility provides significant safety benefits. Smaller scale deli operations are prone to a high incidence of injuries, particularly in the form of cuts or other physical injuries in opening packages, lifting heavy materials, and handling sharp cutting implements.
  • a large scale production facility in contrast, is able to use automation and “hands-free” processes that greatly minimize occurrence of injury.
  • distribution efficiencies can be achieved by providing packaged sliced ready-to-eat meat products as described herein, which are ready for stocking into refrigerated cases at points-of-sale. These packages can be unloaded into the display case at a store by stocking personnel, rather than requiring the attention of persons skilled in the handling of meat products.
  • the supplier can assure consistent product appearance and quality through the delivery of uniformly assembled and handled display-ready packages.
  • the meat to be prepared as ready-to-eat meat may be any meat that is cooked or cured, and suitable for such use. Suitable meats include those obtained from bovine, porcine, equine, caprine, ovine, avian animals, or any animal commonly slaughtered for food production.
  • Bovine animals may include, but are not limited to, buffalo, and all cattle, including steers, heifers, cows, and bulls.
  • Porcine animals may include, but are not limited to, feeder pigs and breeding pigs, including sows, gilts, barrows, and boars.
  • Ovine animals may include, but are not limited to, sheep, including ewes, rams, wethers, and lambs.
  • Poultry may include, but are not limited to, chicken, turkey, and ostrich.
  • the meat is selected from pork, ham, turkey, beef, and chicken.
  • the meat is a sausage meat comprising one or more of the above meats.
  • the meat is selected from only pork, ham, turkey, and chicken, and is not beef.
  • the ready-to-eat meat has been prepared by cooking, such as by roasting, baking or grilling.

  • the meat slices have a major surface area of from about 80 mm 2 to about 180 mm 2 .
  • the ready-to-eat meat is conditioned prior to slicing by any combination of grinding, injecting, macerating, mixing, tumbling, massaging, or stuffing.
  • the meat preparations steps such as macerating or grinding, are carried out to only to the extent desired for conditioning of the meat while substantially maintaining the muscle structure in order to maintain final product cohesive texture properties.

Description

    FIELD
  • The present invention relates to packaged presliced ready-to-eat meat products, and methods of providing such products.
  • BACKGROUND
  • Sliced meat products, such as ham, turkey and fully cooked beef have long been provided in prepackaged form for sale to consumers in grocery stores and the like. Such products often are sold in lidded tray packages that provide a rigid container for a robust packaging system. Such packaging may optionally be hermetically sealed and may even include a modified atmosphere in order to extend shelf life. The modified atmosphere most often includes a gas mixture of carbon dioxide, and nitrogen, or of carbon monoxide, carbon dioxide, and nitrogen. See, for example, Farber, “Microbiological Aspects of Modified-Atmosphere Packaging Technology—a Review,” Journal of Food Protection. Vol. 54. No. I. Pages 58-70 (January 1991).
  • SUMMARY
  • The prepackaged meats as described above are generally not considered to be high quality, premium sliced meat products. In particular, such meats typically are considered to be of ordinary quality. Additionally such meats may contain preservatives that some customers would prefer to avoid, but which provide the conventional, pre-packaged sliced meats available from refrigerated display cases with an extended shelf life of up to 55 to 90 days. Where prepackaged meats are advertised as premium sliced meat products, they are provided in robust packaging materials and hermetically sealed.
  • Meanwhile, high quality sliced, ready-to-eat (i.e. already cooked, cooked and cured, or cured) meat products are conventionally provided in staffed meat outlets, such as butcher shops and deli counters, where the meat is provided to the outlet as sub-primal or large portion cuts that are further sliced by on-site human attendants according to the specific request of the customer. However, time has become a scarce commodity, and there is a great desire to obtain high quality, premium sliced meat products without waiting for extended periods of time at the deli counter.
  • The present invention makes it possible for the customer to obtain a shopping experience that is equivalent to the deli counter experience, while bypassing the inconvenience experienced by delay at the counter. The shopper can quickly select high quality sliced, ready-to-eat meats having an acceptable shelf life from the display case.
  • In an aspect, a method for providing sliced ready-to-eat meat comprises slicing ready-to-eat meat in slices having a thickness of from about 0.5 to 10 mm to provide sliced ready-to-eat meat. The sliced ready-to-eat meat is disposed into a flexible pouch component, which is flushed with a modified atmosphere comprising an inert gas and sealed to provide a sealed flexible pouch containing the sliced ready-to-eat meat and the inert gas. The flexible pouch is formed from a material having:
      • i) a thickness of from about 0.2 mils to about 2 mils;
      • ii) an MVTR of about 1.2 g/100 in2/24 Hrs @100° F., 90% RH, 1 atm or less;
      • iii) an O2 Gas Transmission Rate of about 0.8 cc/100 sqin/day at 0.8 atmosphere, 0% relative humidity and 73° F. or less; and
      • iv) a clarity of about 80% or greater.
  • In an aspect, a packaged sliced ready-to-eat meat product comprises ready-to-eat meat in slices having a thickness of from about 0.5 to 10 mm and a modified atmosphere comprising an inert gas disposed in a sealed flexible pouch. The flexible pouch is formed from a film material having:
      • i) a thickness of from about 0.2 mils to about 2 mils;
      • ii) an MVTR of about 1.2 g/100 in2/24 Hrs @100° F., 90% RH, 1 atm or less;
      • iii) an O2 Gas Transmission Rate of about 0.8 cc/100 sqin/day at 0.8 atmosphere, 0% relative humidity and 73° F. or less; and
      • iv) a clarity of about 80% or greater.
  • The present method and product may afford a number of benefits. In an aspect of the present method, manufacturing efficiencies can be achieved through large scale production of sliced ready-to-eat meats at a centralized production facility. High quality, premium sliced meats can be provided without the loss of productivity, product waste, and variation of sanitation standards that are inevitable from a decentralized and local slicing and packaging operations. In particular, it is noted that carrying out the slicing and packaging operations in a large scale production facility provides significant safety benefits. Smaller scale deli operations are prone to a high incidence of injuries, particularly in the form of cuts or other physical injuries in opening packages, lifting heavy materials, and handling sharp cutting implements. A large scale production facility, in contrast, is able to use automation and “hands-free” processes that greatly minimize occurrence of injury. In an aspect of the present method, distribution efficiencies can be achieved by providing packaged sliced ready-to-eat meat products as described herein, which are ready for stocking into refrigerated cases at points-of-sale. These packages can be unloaded into the display case at a store by stocking personnel, rather than requiring the attention of persons skilled in the handling of meat products. Moreover, the supplier can assure consistent product appearance and quality through the delivery of uniformly assembled and handled display-ready packages.
  • It has been found that placing high quality meat slices in flexible pouches exhibiting the characteristics of flexibility, MVTR, O2 Gas Transmission and clarity provide the ultimate consumer with the experience of obtaining a product that delivers a deli counter quality experience, while at the same time providing the convenience of a self-service display case in a supermarket, large scale retailer or convenience store.

Examples of such packaging systems are described, for example, in WO 2015/002963 and in U.S. Pat. No. 8,357,414 to Becraft, the disclosures of which are incorporated by reference herein.
  • The thus prepared product is shipped to a retail customer under appropriate shipping conditions (e.g. temperature control) to a retail customer.
  • As used herein, the terms “about” or “approximately” mean within an acceptable range for the particular parameter specified as determined by one of ordinary skill in the art, which will depend in part on how the value is measured or determined, e.g., the limitations of the sample preparation and measurement system. Examples of such limitations include preparing the sample in a wet versus a dry environment, different instruments, variations in sample height, and differing requirements in signal-to-noise ratios. For example, “about” can mean greater or lesser than the value or range of values stated by 1/10 of the stated values, but is not intended to limit any value or range of values to only this broader definition. For instance, a concentration value of about 30% means a concentration between 27% and 33%. Each value or range of values preceded by the term “about” is also intended to encompass the embodiment of the stated absolute value or range of values. Alternatively, particularly with respect to biological systems or processes, the term can mean within an order of magnitude, preferably within 5-fold, and more preferably within 2-fold, of a value.
  • Throughout this specification and claims, unless the context requires otherwise, the word “comprise”, and variations such as “comprises” and “comprising”, will be understood to imply the inclusion of a stated integer or step or group of integers or steps but not the exclusion of any other integer or step or group of integer or step. When used herein “consisting of” excludes any element, step, or ingredient not specified in the claim element. When used herein, “consisting essentially of” does not exclude materials or steps that do not materially affect the basic and novel characteristics of the claim. In the present disclosure of various embodiments, any of the terms “comprising”, “consisting essentially of” and “consisting of” used in the description of an embodiment may be replaced with either of the other two terms.
  • All patents, patent applications (including provisional applications), and publications cited herein are incorporated by reference as if individually incorporated for all purposes. Unless otherwise indicated, all parts and percentages are by weight and all molecular weights are weight average molecular weights. The foregoing detailed description has been given for clarity of understanding only. No unnecessary limitations are to be understood therefrom. The invention is not limited to the exact details shown and described, for variations obvious to one skilled in the art will be included within the invention defined by the claims.
